9 Best Science Activities at Home With Kids

Science experiments are so fun to do with friends and family. Here are the 9 best science activities at home with kids that can be done with ingredients you probably already have! There are some free printables too so that is a bonus, right?

Okay, let’s jump in to some experimenting!

Dinosaur Toothpaste (also known as Elephant Toothpaste)

Materials

Empty 20-ounce container

3% hydrogen peroxide solution

Packet of active yeast

Liquid dishwashing detergent (Dawn works great)

Warm water

Food coloring (optional, but makes it lots more fun)

Make Dinosaur Toothpaste

Pour 1/2 cup hydrogen peroxide solution, 1/4 cup soap, and a few drops of food coloring into the bottle. Swirl the bottle around to mix the ingredients all up together. Set the bottle in a sink or outdoors or some other place where you won’t mind a mess being made!

In a separate container, mix a packet of active yeast with a little warm water. Give the yeast about five minutes to activate before proceeding to the next step.

When you are ready to do the demo, pour the yeast mixture into the bottle. The reaction occurs immediately upon the addition of the yeast.
